The transfer window has more thrills and spills than a day at a theme park but we'll holding your hand from start to finish as we get ready for another white-knuckle ride.

Celtic have made a trio of signings so far in Oliver Burke, Timothy Weah and Vakoun Issouf Bayo and are also after Olympiakos defender Omar Elabdellaoui. A deal is set to be wrapped up for Andrew Gutman and Manchester United midfielder Scott McTominay is a loan target. Ukraine winger Maryan Shved has also reportedly been offered to the Scottish champions.

Rangers have secured Jordan Jones and Glen Kamara on pre-contracts - but could the latter arrive at Ibrox this month? Matt Polster has been offered a contract, Jordan Rossiter is wanted by Dundee United and Macedonian teenager Mile Todorov is on trial at Auchenhowie.

Ryan Hardie penned a one-year extension at Ibrox before he was immediately loaned back to Livingston for the remainder of the season.

Aberdeen boss Derek McInnes is looking to make a splash but his biggest challenge could holding onto Gary Mackay-Steven and Graeme Shinnie - who are both out of contract in the summer.

Hibs are close to landing Geneo midfielder Stephane Omeonga on loan from Hibs while St Johnstone have brought back Michael O’Halloran.

I like him, he’s a hard worker. He’s not going to knock the walls down straightaway, but we need strikers.

That’s going to be the difference at the end of the season, whether we can score enough goals.”

Adrien Rabiot has been banished to the reserves as his Paris Saint-Germain future hangs by a balance.

The French midfielder left the club’s winter training camp in Qatar early for family reasons and is now training with the team’s second string.

Rabiot is out of contract at the end of the season with Barcelona and Liverpool leading the chase for his signature.

His manager Thomas Tuchel said:

I have to prepare my team against Guingamp and it will be a team without Adrien. I respect the decisions of the club and this is a decision of the club.

Barcelona were forced to deny they had already agreed a deal with the Frenchman.

They said last year:

In relation to news which has appeared in France, FC Barcelona manifest that the club has not broken any rules in reference to signing players from PSG. The only contact took place in August and again one week ago.

On both occasions the contact was with PSG to express the club’s interest in the player Adrien Rabiot.

FC Barcelona have always wanted to operate with maximum transparency with PSG and all other clubs. FC Barcelona deny the existence of any type of agreement with PSG player Adrien Rabiot.

Accies kid Breen 'Edin to City

Hamilton midfielder Jack Breen has joined Edinburgh City until the end of the season.

The 19 year old began his career at Hibs before moving to Accies at the start of last season. City manager James McDonaugh said:

Jack comes to us at a crucial time of the season where we need to add not just numbers but also quality to compliment what we have in the group. I’m aware of his qualities having previously worked with him and I hope he can benefit his career from his loan spell with us as much as we benefit from having him

DONE DEAL! Celtic's Aitchison moves to Alloa on loan

(Image: SNS Group)

Celtic’s Jack Aitchison has joined Alloa Athletic on loan until the end of the season.

The 18-year-old is highly rated by the Hoops, and the Scotland under-19 international will now get some game time at Jim Goodwin’s side.

The Wasps forward line was weakened earlier today after Greig Spence moved to Arbroath on an 18-month deal.

Aitchison moved on loan to League One side Dumbarton earlier in the season, making five appearances for the Sons.

DONE DEAL! Forrester seals USA move

Harry Forrester has moved to America, after signing with Orange County SC.

The former Rangers and Kilmarnock player moved to Iranian side Tractor Sazi on a two-year-deal after leaving Ibrox in the summer.

He failed to impress there however, making just two appearances for the club, before being loaned out to Machine Sazi, failing to play a game there.

His contract was cancelled by the Iranian side last month, and he has now moved to the States. No details were disclosed by the club about the length of his contract.

Head coach Braeden Cloutier told the club’s website:

I’m very excited to bring a player of Harry’s caliber on board and continue to strengthen our team from a year ago.

One of our first priorities this offseason was to find a dynamic winger with the ability to create off the dribble.

Harry has that quality and proved it at a very high level for Rangers, one of the biggest clubs in the Scottish Premier League.

Forrester added:

I can’t wait to get started, after speaking to Oliver, Braeden, Peter, and Richard, I can see the plans for the club moving forward and I’m excited to be a part of that.

The club and league is only going one way and I want to be a part of that journey.

DONE DEAL! Brian Cameron extends Elgin City stay

Elgin City stalwart Brian Cameron has extended his stay at Borough Briggs for another two years.

The midfielder made his debut for City back in April 2008, smashing the club’s record league appearances for his hometown club.

Claudio Ranieri has admitted for the first time that Fulham’s bid for Gary Cahill is in trouble.

The Whites have been trying to sign the centre-back for the past three weeks.

Chelsea aren’t standing in his way but the 33-year-old’s willingness to join their battle for Premier League survival has seemingly been called into question.

Ranieri said: “Gary is a very important player and for us, it would be fantastic.

“But I don’t know if he wants to come and fight with us.”

DONE DEAL! Anton Ferdinand extends St Mirren stay

And it’s now official.

St Mirren have announced Anton Ferdinand has signed a contract extension until the end of the season.

The defender revealed earlier on social media that he was staying with Saints, and it’s now been confirmed officially.

Saints manager Oran Kearney was delighted to finally get the deal over the line.

He told the club’s website:

It’s taken a bit of time, but we’ve had respect for Anton and he has been respectful for us as well.

His presence about the place has been brilliant both on and off the pitch.

It’s a big boost for everybody to have him stay on-board.

McGregor urges Scott Brown to stay at Celtic

(Image: SNS Group)

Celtic skipper Scott Brown is reportedly moving closer to a move to Western Melbourne in Australia. The Aussies’ nterim chief executive Maurice Bisetto suggested in the Sydney Morning Herald that a deal was getting closer.

And Callum McGregor admits the loss of the 33-year-old midfielder would be a significant blow to the Parkhead club. He said:

He has been a massive part of this club for 11 years and if you ask any player in there in terms of the character and how good a player he is, he would be a massive loss for Celtic.

I think we would be doing everything we can to keep him. He is such a big character on and off the field. He helps everyone, older lads, and younger lads coming through.

He is that figurehead for the boys in the changing room. Ask any player, they definitely want him to stay.

McInnes: Stewart had offers from elsewhere but chose Aberdeen

The winger, who starred for Kilmarnock during the first half of the campaign, signed a temporary deal with the Dons earlier today until the end of the season.

The Reds manager was delighted to secure the Birmingham City forward’s services, although he didn’t reveal which clubs were after the 28-year-old.

He told the club’s official website:

I’m delighted we’ve managed to secure the services of Greg until the end of the season.

He’s a player we enjoyed working with before and he’s been in fantastic form recently and hopefully he can carry that on for Aberdeen.

Greg had offers from elsewhere but he chose us, which says a lot about him and about Aberdeen Football Club, and I’m looking forward to him being a prominent player for us in the second half of the season.

Gary Caldwell says there’s still funds to bring in more signings for Partick Thistle this month.

The Jags are struggling at the wrong end of the Championship just after the halfway point.

The former Celtic and Wigan Athletic midfielder has had a busy January overhauling his squad, bringing in six new players already.

And that number is set to rise over the next few weeks.

The Partick Thistle manager told the club’s official site:

We’ve had a few players leave the club this month which means there are still funds there for me to use.

We do still need at least another couple of bodies in to improve the squad and we’re constantly looking for the right signings.

We had a clear plan at the start of the window which has put us in good stead in terms of transfer dealings but that plan hasn’t been completed yet.

Mourinho’s ex-assistant lands job

(Image: Getty Images)

Rui Faria has been announced as Qatari side Al Duhail’s head coach as Jose Mourinho’s right-hand man takes his first step into management.

The Portuguese left Manchester United in the summer after two seasons at Old Trafford and 17 years working with Mourinho.

Faria had since been linked with a variety of jobs and - a month to the day after his mentor’s sacking by United - has now been confirmed as the head coach of Al Duhail.

The Qatari Stars League champions said they beat off “great European offers” from a number of clubs that either wanted him as the main man or to join their coaching staff.

Mourinho is also in Qatar right now working with beIN SPORTS and Faria is due to hold a press conference in the upcoming days.

DONE DEAL! St Mirren bring in goalkeeper Holmes

Busy few minutes in the Premiership!

St Mirren manager Oran Kearney has brought in goalkeeper Jordan Holmes on loan from Bournemouth until the end of the season.

The 21-year-old Australian has been with the Cherries since 2013, and has had several loan spells out to Weymouth and Eastbourne Borough.

Kearney told the club’s official website:

It’s all happened quite quickly.

Obviously Danny Rogers was out for a period of time earlier in the season with a knee injury and he has hurt the knee again. There’s been a scan there and it looks like he might be out again for another period of time.

With that it opens the door for Jordan. He is someone we know through sources in the game and has a good pedigree. He was keen to come up and is looking to forge a good career in the game for himself.

He’s the Buddies’ second signing of the day, after Kyle McAllister sealed a loan switch back to his old club from Derby County.

And perhaps Anton Ferdinand signing a new deal later on..? Busy day for Saints regardless!

DONE DEAL! Aberdeen sign Stewart

Aberdeen have completed the signing of Greg Stewart on loan until the end of the season.

The forward - who shone on loan at Kilmarnock in the first half of the campaign - has returned to Pittodrie after spending last season on loan with the Dons.

Stewart returned to Birmingham at the turn of the year after Brum cut his spell at Killie short. It had been thought the St Andrews side were looking to offload the 28-year-old.

But it’s understood Aberdeen convinced Brum to send the player back north with an offer to pay more of his wages than Killie.

Stewart is out of contract in the summer when he could make the Pittodrie switch permanent. He was utilised more in the wide areas by Derek McInnes in his first spell up north but appeared far more effective through the middle with Kilmarnock, scoring eight goals so far this season.

16:05

DONE DEAL! Michael Smith signs new Hearts contract

Hearts have announced Michael Smith has extended his current contract until May 2021.

The Northern Ireland international’s old deal expired at the end of the season, but he will now stay at Tynecastle for two more seasons.

Manager Craig Levein told the club’s official website:

I believe Michael has improved as a player since joining the club, which is reflected by the fact he has earned several international caps for Northern Ireland during his time here.

Michael’s performances this season speak for themselves. He’s been playing to a very high level week in, week out and I am delighted that he has committed his future to Hearts until 2021.

Crystal Palace will resist any Manchester United move for their right-back Aaron Wan-Bissaka.

The Mirror Sport revealed this week that United want to lure the highly-rated 21-year-old to Old Trafford.

Manchester City and Chelsea are also said to be interested in the full-back, who only signed a new deal at Selhurst Park last April.

But Palace are in no mood to let Wan-Bissaka go and the Evening Standard say they will fight all the way to keep him in south London.

DONE DEAL! Watters heads to Stenhousemuir

Former Motherwell and St Mirren youth product Ryan Watters has sealed a move to Stenhousemuir.

The 20-year-old spent the first half of the season at Albion Rovers, scoring twice in 15 appearances.

Watters becomes the third signing of the transfer window for Warriors manager Colin McMenamin, and he will be in the League Two side’s squad for the Scottish Cup tie against Aberdeen tomorrow.

DONE DEAL! Queen's Park return for Galt

The midfielder left the club last summer to join Championship side Alloa Athletic, but he failed to make an appearance for Jim Goodwin’s side.

The 28-year-old moved to junior side Cambuslang Rangers recently, but has sealed his return to the League Two side.

Hodson’s Ibrox career is all but over with his contract expiring in the summer.

Marko Arnautovic will not be moving to China this January.

The West Ham forward was the subject of a £35million bid from an unknown Chinese Super League club last week which was subsequently rejected.

The Irons are desperate to keep hold of their joint-top scorer who they secured for a club record £25m in 2017.

It is understood that the unnamed club will not be coming back with a second bid.

DONE DEAL! Kyle McAllister makes St Mirren return

St Mirren have confirmed the return of Kyle McAllister on loan from Derby until the end of the season.

The 19-year-old left Paisley in the summer of 2017 but is now back to help give Oran Kearney’s side a jumpstart in their bid to avoid the drop.

Manager Oran Kearney is over the moon to secure McAllister’s services, he said:

I’m very pleased to have Kyle in.

Number one you want to get good players in, but I also think it’s very important to have people who have come through the club and know what it is about.

Kyle had a great start to his career here and got his move to Derby. He’s someone I’ve been aware of since I joined the club with people talking about him. He’s fully fit at this point in time and we can’t wait to get him in and get him started.

We are still in the market for more width as we lack those ball carriers, those wide players who can go and unlock defences and Kyle definitely ticks that box so it’s brilliant from that point of view to get him in as well..

Josh Maja latest

(Image: Getty Images)

Sunderland boss Jack Ross admits he is “fed up” over speculation surrounding wantaway Josh Maja and is desperately seeking a resolution to the striker’s future.

Celtic are reportedly keen on the 20-year-old - who is out of contract in the summer.

Maja has netted 15 times in all competitions but he looks almost certain to leave the Stadium of Light.

Ross said:

First of all, there’s no change in Josh’s situation.

Secondly, there has been absolutely no approach for him or formal communication from any other club.

That is me being entirely truthful.

There may have been communication from other clubs to Josh via third parties - that happens - and I’m not crying about that because that happens in football all the time, and what that might potentially lead to I have no idea.

What I would say is that I’m starting to edge towards the stage where I am fed up with it and I think we need to resolve it one way or the other and have clarity about what is going to happen.

There are a few different potential scenarios in that - Josh leaves, Josh stays, Josh signs a new contract, Josh leaves and comes back on loan - but we need to get to one, because it is dragging on and I need to know to allow me to plan.

I’ve been quite open about our hunt for a striker but that is if Josh stays. If Josh goes, it becomes two [strikers] and that’s not easy to do in 14 days.

We’re finding it hard enough [to get one] at the moment, without having to find two.
